Watching this speedrun while working this morning really brought back some great memories. I think this is my favorite Super Mario Brothers game if not the best one.
I think a lot of people might say Super Mario World is the best Mario game. Not really familiar with the debate around the best Mario games but I think my ranking here is a mix of nostalgia and just the relaxing, no-timer play that feels very Metroid Vania, even though technically this isn't a Metroid Vania.
Maybe "feels like" is my standard for what video games I really love?
